TRAP:
  • This interrupt is a non-maskable interrupt. It is unaffected by any mask or interrupt enable.
 
  • TRAP bas the highest priority and vectored interrupt.
 
  • TRAP interrupt is edge and level triggered. This means hat the TRAP must go high and remain high until it is acknowledged.
 
  • In sudden power failure, it executes a ISR and send the data from main memory to backup memory.
 
  • The signal, which overrides the TRAP, is HOLD signal. (i.e., If the processor receives HOLD and TRAP at the same time then HOLD is recognized first and then TRAP is recognized).
 
  • There are two ways to clear TRAP interrupt.
 
               1.By resetting microprocessor (External signal)
               2.By giving a high TRAP ACKNOWLEDGE (Internal signal)
